The Louisiana Department of Transportation and Development (LaDOTD) has requested approval from the Senate and House chairmen of the Committees on Transportation, Highways, and Public Works to execute a public-private partnership (P3) contract with Calcasieu Bridge Partners for the replacement of the I-10 Bridge over the Calcasieu River, Canada.

The existing bridge, which is over 70 years old, lacks shoulders, and has steep approach grades, is in need of replacement. If a new project is not initiated soon, a significant and likely costly repair effort will be required to maintain the bridge's functionality. The US$ 2.1 billion project has faced opposition, especially concerning the toll rates for the new bridge. These toll rates are essential to fund the project and are comparable to, and sometimes even lower than, those on similar toll bridges nationwide. While the toll rates are reasonable, both DOTD and Calcasieu Bridge Partners are actively exploring options to potentially reduce or eliminate tolls for local passenger vehicles. The LaDOTD is currently planning to replace the I-10 Bridge over the Calcasieu River. The new bridge will be a cable-stayed bridge with a main span of 1,700 feet (520 m). The new bridge is expected to be completed in 2027.

The I-10 Bridge over the Calcasieu River is a six-lane cantilever bridge that carries Interstate 10 over the Calcasieu River in Lake Charles, Louisiana. The bridge is 6,617 feet (2,017 m) long and has a main span of 1,033 feet (315 m). The bridge was opened to traffic in 1952 and was originally designed for a capacity of 15,000 vehicles per day. However, traffic volumes have increased significantly over the years, and the bridge is now carrying over 60,000 vehicles per day.
